17 Object Types

The Expression Filter feature supplies a set of predefined types and public synonyms for these types. Most of these types are used for configuring index parameters with the Expression Filter procedural APIs. Use the EXF$TABLE_ALIAS type to support expressions defined on one or more database tables. Table 17-1 describes the Expression Filter object types.

None of the values and names passed to the types defined in this chapter are case sensitive. To preserve the case, enclose the values with double quotation marks.

Tip:

See the chapter describing the Expression Filter Object Types in Oracle Database PL/SQL Packages and Types Reference for all reference information concerning Expression Filter object types. Use the links in the Object Type Name column in Table 17-1 to see each object type.
